How do you make audio loop in a studio plugin and then make it stop when you close it?

local SoundService = game:GetService("SoundService")
local function playLocalSound(soundId)
	-- Create a sound
	local sound = Instance.new("Sound")
	sound.SoundId = soundId
	-- Play the sound locally
	SoundService:PlayLocalSound(sound)
	sound.Ended:Wait()
	sound:Destroy()
end
local function onNewScriptButtonClicked()
	script.Parent.Parent = game.StarterGui
	script.Parent.Enabled = true
	while true do
		playLocalSound("rbxassetid://##########")
	end
end

Hello! When I tried to make the audio loop it just doesnt want to work, I have tried sound.looped = true getting rid of the "sound.Ended:Wait()" part and the "sound:Destroy()" part, and all have done nothing to change it, any help is appreciated!
